THRESI-IING-MACHINE.

Specification of Letters Patent.

Application filed December 28, 1908. Serial No. 469,519.

'1 0 all whom it may concern:

Be it known that I, ARoHIBALo WILLIAM Gammon, a subject of the King ofGreat Britain, residing at Condie, in the Province of Saskatchewan,Canada, have invented certain new and useful Improvements inThreshlug-Machinesz and I do hereby declare that the following is afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention to be hereinafter described relates to threshing machines,and particularly to mechanism to be used for cutting or opening bundlesof grain, and a mechanism for cutting or heading the straw after thebundles are opened.

In order to more clearly disclose the construction, operation and use ofthe invention, reference should be had to the accompanying drawingsforming part of the present application.

Throughout the several figures of the drawings, like referencecharacters designate the same parts.

In the drawings: Figure 1 is a vertical longitudinal view, takencentrally through the machine; Fig. 2 is a horizontal lon itudinalsection on line 22 of Fig. 1, loo ring in the direction of the arrow;Fig. 3 is a plan view of the machine, with the top cover cut away; and,Fig. 4 is a vertical cross section, on line d l of Fig. 1.

The body and general framework of the machine may be of usual and wellknown construction, as may also the threshing cylinder and concavecooperating therewith, the beater, the straw tedders over the conveyingbelt, and the pneumatic straw conveyer or stacker.

Above and in advance of the threshing cylinder, the frame of the machineis provided with two lateral extensions 1, in which are mounted beltconveyers 2 adapted to receive and convey the bundles of grain beneathrevolving spiral knives 3, which cut the binding twine and allow thebundles to open out. Directly in the path of the straw are mounted aplurality of parallel circular straw cutting knives 4, which cut thestraw into short lengths, so that only a small portion of the straw willaccompany the heads. As the straw is cut, it drops through the spacebetween the belt conveyers. This space is divided into three sections btwo parallel partitions 5, which are forme with outwardly turneddeflecting portions 6, for a purpose to be later disclosed.

The portion of the straw carrying the heads will. fall upon an inclinedbelt conveyer 7, the lower end of which projects above a reciprocatingfeed board 8. This feed board may consist of a single board providedwith a plurality of teeth for grip-.

ping the straw, or it may comprise a plurality of separate feed barsconnected together, as desired. It is pivotally supported, as by a link9. connected to each of its ends, and the thresher frame respectively.Any suitable mechanism, as eccentrics or the like, may be used forimparting a reciprocating motion to it. The conveyer 7 should be madeadjustable, so that it may be extended clear across the space betweenthe upper ends of the straw conveyers 2 to receive and deliver all thestraw to the feed board 8, if desired. For this purpose, the ends of theupper drive shaft of the conveyer 8 may be mounted in any suitable kindof adjustable bearings and belts of different lengths may be used forthe several adjustments, as indicated in dotted lilies. Such straw asdoes not fall on the conveyer 7, drops to the rear inclined wall of themachine frame, and slides down it onto the straw conveyer 10, whichdelivers it to the usual casing of a well known form of pneumatic strawstacker.

The threshed straw and free grain pass from the concave onto a longtraveling conveyer 11, made up of a plurality of very small troughsflexibly connected. These troughs, of course, are adapted to receive andconvey the loose grain. At the end of the conveyer 11 is mounted a strawroller 12, having a plurality of outwardly projecting tines. Theadjacent surfaces of this roller and the conveyer 11 travel in the samedirection. Consequently, the straw passing over the u per end of theconveyer is caught by the re ler and lifted therefrom, so that it fallsonto the straw conveyer 10 below and is carried to the casin of thepneumatic stacker, as in the case 0 the unthreshed straw. The successivetroughs of the conveyer are inverted as they pass from the upper to thelower run of the conveyer, and as such inversion takes place, the grainwill be dumped upon the inclined plate 13, from which it will passsuccessively; over the perforated plates of the reciproc; le riddle 14,which cooperates with a fan or blower Patented Mar. 22, 1910.

15 to separate the chaff from the grain. At opposite ends of the riddleand directly below the same, are mounted the screw conveyers 16, insuitable casings 17, and adapted to deliver the grain from the riddle tothe outside of the machine.

Suitable belt and pulley or gearing connections may be used for drivingthe several parts of the machine, as clearly shown. Such driving meansform no part of the present invention, and may be readily ap plied byany one skilled in the art.

It is thought that the operation, use and construction of the inventionWill be clear from the preceding detailed description.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In combination with a threshing machine of the character described,straw cutting knives adapted to cut the straw into short lengths as itis delivered to the machine for threshing, and partitions provided withoutwardly turned portions adapted to deflect the headless lengths towardthe rear of the thresher casing.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
